How to install the protective door of the elevator?

There are two kinds of elevator protective doors, one is frameless, and the other is framed. Let's talk about frameless elevator protective doors. There is a 19-cm round tube on all sides of frameless elevator protective doors. After the goods are delivered to the construction site, just weld four L-shaped hooks on the elevator scaffolding, and then hang the elevator protective doors. There is a horizontal steel pipe above the protective steel door, which is not more than 1.8m from the platform ground and the length of the steel pipe is not less than 1.5m.: The side of the protective door is provided with two bolt shaft holes welded by Ф2 steel pipe; Using Ф12 steel bars, the portal shaft is processed by a steel bar bending machine, and the length of the bending part is not less than 14 cm. One side of the bending part is welded to the corresponding position of the steel pipe upright post of the platform scaffold, and the bending part at one end is fully welded with the steel pipe upright post, and the other end is used as the portal shaft; In the process of welding the door shaft, pay off the position of the door shaft in advance, and carry out welding operation after verification, and pay attention to construction safety during welding; Before installing the protective door, you should brush the protective paint of the protective door and spray the enterprise logo

on the outer side of the protective door; The door frame and the external elevator platform frame are firmly welded by electric welding, and the weld length of the welded part is not less than 14 cm; ?

welding requirements: all welds must be welded firmly, and the appearance quality of the weld shall meet the following requirements: the weld shall be designed as a first-class weld, and there shall be no defects such as incomplete welding, root shrinkage, undercut, and non-fusion, and there shall be no defects such as surface blowholes, slag inclusion, cracks and arc scratches when entering the construction site. Safety helmets must be worn, and safety belts and anti-slip shoes must be fastened for high-altitude operations and edge operations; The electricity used for construction shall meet the requirements of the current Technical Specification for Safety of Temporary Electricity Use in Construction Sites, and attention shall be paid to welding sparks during welding.
